Current CPU Temperature Detect CPU temperature automatically. Current CPU/SYSTEM FAN Speed (RPM) Detect CPU/SYSTEM fan speed status automatically. CPU Smart FAN Control Eabled Enable the CPU Smart FAN Control function. (Default Value) a. When the CPU temperature is higher than 65 degrees Celsius, CPU fan will operate at full speed. b. When the CPU temperature is between 20 and 65 degrees Celsius, the CPU fan speed will change depending on the actual CPU temperature. c. When the CPU temperature is lower than 20 degrees Celsius, CPU fan will stop spinning. Disabled Disable the CPU Smart FAN Control function. CPU Smart FAN Mode This option is available only when CPU Smart FAN Control is enabled. Auto BIOS autodetects the type of CPU fan you installed and sets the optimal CPU Smart FAN control mode for it. (Default Value) Voltage Set to Voltage when you use a CPU fan with a 3-pin fan power cable. PWM Set to PWM when you use a CPU fan with a 4-pin fan power cable. In fact, the Voltage option can be used for CPU fans with 3-pin or 4-pin power cables. However, some 4-pin CPU fan power cables are not designed following Intel 4-wire fans PWM control specifications. With such CPU fans, selecting PWM will not effectively reduce the fan speed. - 39 - BIOS Setup
